I am using Mathematica 4.1, but I suspect all versions do the same in this case. In[1]:= Infinity + Pi * I Out[1]= Infinity I think it the input above should return itself. Am I wrong here? If we do it my way the following would return -Infinity. (*Negative Infinity*) In[1]:= E^( Infinity + Pi * I ) Out[1]= Infinity Either way it's an interesting example. ------- Regards, Ted Ersek
